Don't you ever confused those 3G ,4G Broadband Standard listed on the phone specification? Below provide some information about the broadband standard use by TEL CO .
First, Let look at CDMA2000, also known as EVDO, CDMA 1X ,It all catogorise under CDMA ,it's not 3G
You can Refers to the CDMA2000 EVDO data network at WIKI to know more on this Standard.
HSDPA refers to an upgraded version of the 3G network, commonly known as 3.5G, 3G networks can provide much faster than the average transfer rate that 2.5 G EDGE.
HSUPA refers to the" speed up "version of HSDPA 3.5G networks ,it provide faster transfer rate than HSDPA network bandwidth
GSM refers to what we commonly referred to as 2G, Mobile
GRPS is the GSM data network, providing low-speed data transmission services;
EDGE is an upgraded version of GRPS provides faster transmission speed than GPRS, the fastest 230K
WLAN refers to a wireless LAN aka wireless area network
WIFI is one of the most common type of WLAN, the wireless router's signal is the WIFI signal transmitting
WAPI is a WLAN, WIFI, and almost the same standard ,it enhance with password validation functions, WIFI and WAPI are compatible
WiMax is a quasi-3g technology, there is no official international standard for 3G
Check out the progress for the GSM tecnologic recent year :
GSM → GPRS → EDGE → WCDMA → HSDPA → HSUPA → HSPA+ → LTE FDD
HSPA+, or Evolved High-Speed Packet Access, is a technical standard for wireless, broadband telecommunication. HSPA+ was first defined in the technical standard 3GPP release 7.
HSPA+ provides an evolution of High Speed Packet Access and provides data rates up to 84 Megabits per second (Mbit/s) to the mobile device and 22 Mbit/s from the mobile device. Technically these are achieved through the use of a multiple-antenna technique known as MIMO (for “multiple-input and multiple-output”) and higher order modulation (64QAM) or combining multiple cells into one with a technique known as Dual Cell.(WIKI)
